Not my day today! Pre-patch save games won't work so i decided to start a new game. Get through all the boof at Doc Mitchells and now i cant get in the saloon to see Sunny as it crashes everytime I enter! I don't think i have any mods that effect the saloon in any way. I disabled New Vegas Bounties in case it was the holodisk on the bar causing trouble but this had no effect! :facepalm:

Just an update on this topic as i can't find a solution. I have re-installed New Vegas and taken all mods off. Started a new game and everything seems to be in order. So i am now going to put my mods back on one by one and see if any of them causes the crash i had when entering the Prospector saloon!
